This function tags sources with IR excess based on their colors in Spitzer IRAC bands 1-4. The cut used comes from Megeath et al 2004, ApJS 154:367. Sources are tagged as source 0/I, II, or III/main sequence
A vector of bytes the same length as i1-i4. The value at slot i is 1, 2, or 3 depending on whether the source at slot i has colors like a class I, II or III/Main Sequence star. Only sources marked as 1 or 2 should be considered as candidate excess stars.
